【问题描述】：

我正在使用 VS 代码。在为 web 构建 Flutter 的一些实验之后，它开始为 web 构建每个项目是默认的。我需要恢复默认的 Android 版本。

PS D:\code\2019\dart_app1\app1> flutter devices
2 connected devices:
Windows • Windows • windows-x64    • Microsoft Windows [Version 10.0.17134.984]
Chrome  • chrome  • web-javascript • Google Chrome 76.0.3809.132

>PS D:\code\2019\dart_app1\app1> flutter emulators
3 available emulators:
Nexus_5X_API_29  • Nexus 5X API 29  • Google • android
Nexus_9_API_28   • Nexus 9 API 28   • Google • android
flutter_emulator • flutter emulator • Google • android
To run an emulator, run 'flutter emulators --launch <emulator id>'.
To create a new emulator, run 'flutter emulators --create [--name xyz]'.
You can find more information on managing emulators at the links below:

launch.json:

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Flutter",
            "request": "launch",
            "type": "dart"
        }
    ]
}

【解决方案1】：

在launch.json 文件中使用args 参数指定您的设备：

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Flutter",
            "request": "launch",
            "type": "dart",
            "args": ["-d", "<device name from adb devices output>"]
        }
    ]
}

或从右侧底部面板中的vscode 中选择。默认情况下，启动器选择第一个可用设备，chrome device 可能总是这样。

补充，我使用 fvm 那么路径是fvm/fvm_config.json。泰来帮忙！
